Abstract

The present invention relates to an analyzer and method for simultaneously determining both size and material properties of a single nanoparticle. In the present invention, both the mass of the nanoparticle and the change in capacitance induced on a capacitive sensor by the nanoparticle are measured simultaneously, and thus the size and material properties of the nanoparticle are determined. An analyzer for simultaneously determining the size and material properties of a nanoparticle is described with the present invention, this device comprises a mass sensor, a capacitor sensor and a common precise measurement region of the mass sensor and capacitor sensor, wherein said mass sensor and capacitor sensor provide common measurement. The present invention can be used in the field of biomedical, environmental engineering and materials engineering.
